Bondability of Ti Adherends. III. Oxide Stability and Substrate Corrosion.

Abstract

As the last part of a three-year program designed to evaluate surface pretreatments of titanium for adhesive bonding, this study concentrated on the effect of oxide stability on bond durability. We found that if the oxide is amorphous and highly defective, it will be susceptible to morphological and structural changes. The bond to epoxy, which probably involves only the uppermost atomic layer of the oxide, may be disrupted by surface migration and crystallization in the oxide and by processes leading to the base metal corrosion in water. These mechanisms are known to be highly temperature sensitive and are probably accelerated in the presence of water. The use of Auger electron spectroscopy and sputter profiling for studying oxide transformations is also illustrated.
